2 claims. 1 (o1. :i6-a5) Myinvention consistsin a new and usefulimprovement inshoesand is designed to produce as hoe tobe worn bypersons undergoing treatment'fonsuch deformities of the foot as talipesvarus. and. talipes valgus, in which thev foot is inverted orevertedfrom the normall position. Under the method of treating suchdeformities, asI now practiced, the'foot structure is sodisposed as toeffecta certain-desired relationship between the Vseveral parts, whichrelationship must be maintainedduring a denite period. Thereuponfurthertreatment; produces a new relationship of theparts .which isYmaintained through a definite period.v Such periodic changes in therelationship ofr` the parts of the foot structure may be numerous.`Since the patient requires the use of Va shoe onv the treated footduring the several periods of. treatment, it is Aobvious that there mustbe adequate provision for a-shoe which preciselycorresponds in itscontour with the particular Condition. of the footin each period of thetreatment. Toobviate the necessity of. providing a separate shoedesigned. for the condition of the foot' in each period, I have devisedmy improved'shoe which is so constructed as `to be capable ofmanipulation to produce the proper contour suitable for the foot in eachperiod of treatment. Since the treatment produces variations in therelation of the fore foot to the hind foot, my improved shoe is designedto provide relatively movable fore and hind portions. The structure ofthe sole andupper of my shoe is such that the fore and hind portionsthereof can be manipulated to assume any one of a plurality ofrelations, to produce a shoe having the precise contour demanded by thepeculiar relationship of the parts of the foot structure produced at anyparticular period of treatment. To effect this result, the fore and hindportions of my shoe are pivotally related at a point on the verticalaXis L passing through the calcaneo-cuboid joint of the foot for whichthe shoe is made.

The particularly novel and useful features of my improved shoe are thebi-partite sole and bi-partite upper mounted thereon, and the means forpivotally relating the two portions of the sole. My shoe comprises a twopart outsole, a two part insole, with pivotally related connectingmembers mounted between the respective outsole and insole of each soleportion, a quarter attached to the posterior portion of the sole, and avamp attached to the anterior portion of the sole, the quarter and Vamphaving overlapping portions and means, such as eyelets and lacing, fortemporarily connecting the `quarter and vamp. The connecting members ,ofthe.sole are provided with Ilocking means.. whereby they may be retainedin', determined relations.

Il'have illustrated inthe drawings led herewith, and have hereinafterfully described certain specific embodiments of myinvention', but i1; isto be distinctlyunderstoodthat I donot consider my invention.toVbe'liinited to said specific embodiments, butrefer forvits scope to theclaims appended hereto.

Fig. 10 is a side elevation of the modified form of shoe.

As illustrated in the drawings, my improved shoe comprises thebi-partite sole consisting of the posterior portion A and the `anteriorportion B, and the bi-partite upper consisting of the separate quarter Cand vamp D. Each of the portions A and B comprises the usual outsole andinsole. The outsole l of the posterior portion A has its forward edge 2formed as an arcuate concavity and the outsole 3 of the anterior portionB has its rear edge 4 convexly arcuate to correspond with the edge 2.The outsoles l and 3 have suitably embedded therein and riveted theretothe co-acting pivotally related members 5 yand 6 respectively. Themember 5 and the member 6 are provided with co-acting knurled faces 'land 8 on their upper and lower surfaces respectively. The screwpivot-pin 9 is threaded in the member 5 and its slotted head I0 bears onthe member 6. It is to be noted (Fig. 5) that the members 5 and 6 are sodisposed relative to the outsoles l )and 3 that the member 5 extendsforwardly of Athe junction of the edges 2 and 4, over the outsole 3. Theinsole II of the posterior portion A is mounted on the outsole I andmember 5 and extends forwardly over a portion of the outsole 3, and itsforward edge has an arcuate concavity I2 spaced slightly from the headI0 of the pivotpin 9, and rearwardly inclined shoulders I3. The insoleI4 of the anterior portion B is mounted on the outsole 3 and the member6 and its rear edge has an arcuate cavity I5 spaced slightly from thehead I of the pivot-pin 9, and forwardly inclined shoulders I6. The heelI-I is suitably attached to the posterior portion A.

The vamp D is attached in the usual way to the anterior portion B, itslower rear edges I'I extending slightly rearwardly of the meeting edges2 and 4 of the outsoles I and 3.' The'quarter C is attached in the usualway to the posterior portion A, its forward edges I8 extending over therear of the vamp D somewhat forwardly of the pivot-pin 9, therebycausing the forward portion C' of the quarter C to overlap the rearportion D of the vamp D., It is to be noted that the lacing eyelets I9in the portions C' and D' are disposed in registering positions. Asingle loose inner sole I overlying the portions A and B may beprovided.

In Figs. 9 and 10, I have illustrated a modified form of my improvedshoe. In this form, the forward edge A-I of the posterior portion A ofthe sole and the rear edge B-I of the anterior portion B of the sole arecorrespondingly beveled, thereby providing overlapping areas A-2 andBf-2 of the posterior and anterior portions A and IB' respectively, thepivot-pin 9 being centrally disposed relative to these overlapping areasA-Z and B-2. In this modified form of my shoe, I have shown the rearportion D' of the vamp D enclosing the forward portion C of the quarterC.

From the foregoing description of the details of construction of myimproved shoe, its operation and use will be obvious. Removal of theloose inner sole I renders access to the slotted head Ill of thepivot-pin 9 which maybe rotated by any suitable tool, thereby relievingtension between the faces 'I and 8 of the members and 6. The anteriorportion B with vamp D may then be manipulated, relative to the posteriorportion A and quarter C, so that the shoe assumes the desiredconfiguration. The pivotpin 9 is then rotated by the head I 0, therebylocking the parts to maintain their determined relation. The inner soleI is replaced, and the shoe is ready for use.

Having described my invention, what I claim is:

l. In a shoe, the combination of a posterior outsole portion having aconcave forward edge and a longitudinal recess in its inner faceextending rearwardly from said edge; an anterior outsole portion havinga convex rear edge received in the concavity of the posterior portion.and a longitudinal recess in its inner face extending forwardly fromsaid convex edge, the two recesses being aligned; a lower hinge memberdisposed in the recess of the posterior portion and a portion of therecess of the anterior portion and fixed to the posterior portion; anupper hinge member disposed in the remaining portion of the recess inthe anterior portion and fixed to the anterior portion; and a pintle pinpivotally relating said hinge members.

2. In a shoe, the combination of a posterior outsole portion having aconcave forward edge and a longitudinal recess in its inner faceextending rearwardly from said edge; an anterior outsole portion havinga convex rear edge received in the concavity of the posterior portion,and a longitudinal recess in its inner face extending forwardly fromsaid convex edge, the two recesses being aligned; a lower hinge memberdisposed in the recess of the posterior portion and a portion of therecess of the anterior portion and fixed to the posterior portion; anupper hinge member disposed in the remaining portion of the recess inthe anterior portion and fixed to the anterior portion; a pintle pinpivotally relating said hinge members; a posterior insole portionattached to said posterior outsole portion and extending forwardly overa portion of said anterior outsole portion; and an anterior insoleportion attached to said anterior outsole portion, the two insoleportions having adjacent faces formed to provide a substantiallycircular passage for said pintle pin and V-shaped recesses projectinglaterally from said passage.
